Reset Your HVAC Like a Pro: Expert Tips to Revitalize Your System Instantly!



To answer how to reset the HVAC system, we should first determine, which type of system we have to deal with because each type has its reset process, conditions, and underwater rocks. And before we even start, you should understand the following concepts: what the HVAC system is, what its types are, and how to reboot each.

In a Nutshell: What HVAC System Is?


HVAC is actually an abbreviation of the first letter of words: Heating, Ventilation, and Air Conditioning. Each of the components included in the HVAC system is responsible for the achievement of certain climatic indicators in a room.


  • Heating - maintaining a comfortable temperature inside the building by heating the air. It may be done by heating systems like stoves, boilers, radiators, or heat pumps.
  • Ventilation - circulating and supplying fresh air throughout a building and removal of polluted air. This includes air supply and exhaust processes, the use of air ducts, ventilation grilles, and filtration systems.
  • Air conditioning refers to the process of cooling and reducing the humidity level of the air inside the building in hot conditions or maintaining the optimum temperature. This includes air conditioning systems such as central ducted systems or ductless mini split systems.


Types of HVAC systems


The specific choice of HVAC system type depends on the technical and architectural characteristics and building needs, budget, climatic conditions, and other factors. Systems are selected considering all the requirements, standards, and wishes of the client. And, of course, the budget.


The Most Commonly Used Systems


Each of the HVAC systems has its own characteristics, application, and maintenance features. And knowing the specific system and its operating requirements is crucial in detecting the way how to reset the HVAC system.

  • Central Air Conditioning Systems

A common type of HVAC system that provides temperature change to be comfortable for an entire building through a central unit connected to ducts and ventilation grilles. Found in commercial and residential buildings.


  • Separate Heating and Air Conditioning Systems

This is the case when heating and air conditioning are carried out by separate systems. Heating may be provided by a boiler for example, of stove, or other heating system. While air conditioning is provided through separate air conditioners or heat pumps.


  • Geothermal Systems

Considered energy-efficient systems that use the earth or soil as a source of heat or cooling. They use heat pumps to pump heat or cold from the ground inside a building.


  • Radiator Heating Systems

This is a type of heating system transferring the heat through radiators located indoors. They are often used in old or traditional buildings.


  • Ventilation Systems

These systems are designed to ensure the circulation of fresh air within a building and to eliminate or reduce the presence of contaminated air, not cooling or heating it. They can be part of an HVAC system or work independently.


  • Ductless Mini Split Systems

These are air conditioning systems that operate without the need for traditional ductwork. They consist of separate indoor units installed in each room or zone, and an outdoor unit connected to them by pipes for transferring cold or hot air. 


Now to the Point: How to Reset HVAC System


The first and foremost annoying question of any hotline “Did you reset HVAC system” may be just not relevant in this case. Whatever the type of system installed in your building, almost no one has a universal "reset" button. There are significant differences in the preparation, implementation, and diagnosis of reset not only of different types of HVAC systems but also depending on the type of building where they are installed.


Small Facilities


In smaller facilities with smaller and more decentralized HVAC systems, the process on how to reset HVAC system can be easier and more straightforward. However, even small resets require post-reset checks and adjustments to make sure the system is working properly:


1. Turn off your HVAC system: switch or remote control, or unplug the power cord from the socket.

2. Wait a few minutes to allow the system to completely shut down and drain.

3. Turn on the power to the HVAC system using the turning-off method.

4. Check the operation of the equipment: after turning on the power, check if the system starts to work normally. Check that all functions such as cooling or heating are working properly. 


If the error or failure still occurs, contact us as a certified technician to solve any accrued problem. Please, do not unwind or disassemble the equipment by yourself! Because any unauthorized tampering with structure or settings will void warranty coverage and may increase repair costs and even total damage to the HVAC system.


Large Facilities


In large facilities where with installed centralized HVAC systems, the process on how to reset HVAC system is more complex and time-consuming, and requires the intervention of qualified technical personnel or HVAC specialists to reset the system and verify its operation after that. Such systems usually have many components, including large air conditioners, air handling units, ventilation systems, and so on. 


Important: when resetting large HVAC systems, the presence and training of qualified HVAC technicians or specialists may is required! The process itself consists of the following steps: 


1. Turn off the power of the HVAC system: turn off the accordant switches in the electrical panel.

2. Wait for a while to allow the system components to completely shut down and run out of charge.

3. Turn the power to the HVAC system on. To do that, press the switch again or use the remote control.

4. Check operation: After turning on the power, perform a functional check of the system and its components. Make sure all functions work correctly and there are no problems or errors.


Please note that we described only general steps, and the process on how to reset HVAC system varies depending on the specific model and configuration of the system.


How to Reset HVAC System: The Easiest and Most Direct Way


Let’s be reasonable: not a single system problem might be solved by simply turning the power on and off. Most often, any, even the smallest breakdown is a signal that the system is on the way to failure. Regardless of the size of the system and the purpose of the building where they are installed, rebooting or resetting your specific HVAC system requires attention to detail, knowing the manufacturer's instructions, and special skills for further safe and efficient system operation. Always refer to the documentation or user manual for exact instructions on how to reset HVAC system. But the most reasonable and justified decision would be to call us to avoid damage, voiding the warranty, or total HVAC system failure.
